Gulfsands tastes gas at Morocco onshore drill

06th January 2015

Gulfsands Petroleum has completed drilling operations on the Dardara Southeast 1 well (DRC-1), located within the Rharb Centre Permit in Northern Morocco

The DRC-1 well was drilled to a Total Depth (TD) of 1,153 metres Measured Depth (MD) and encountered the primary reservoir target interval on prognosis at a depth of 875-metres MD.

Significantly elevated gas readings obtained while drilling, as well as interpretation of geological samples and wireline logs, indicate the presence of a gas bearing sandstone reservoir section of excellent quality.

"We are delighted with the results of the drilling operations and petrophysical evaluation of the DRC-1 well which point to it being the best exploration success that the company has achieved in Morocco to date,” said Mahdi Sajjad, Gulfsands CEO.

“We look forward to completing the well and observing the production performance during well clean-up operations. The results have given us a firmer understanding of the local geology and the indication of further gas exploration potential to exist up dip in the Dardara South East structure is particularly pleasing."

Detailed petrophysical evaluation of DRC-1 wireline logs yield an initial interpretation indicating a 53-metres gross thickness of excellent quality reservoir sand between 875-928 metres MD, with a net gas bearing sand thickness of 16 metres, evaluated average gas saturation of 68 per cent and average porosity of 34 per cent.

A gas-water contact has been observed in the well at approximately 895-metres MD as evidenced by wireline log and formation pressure data.

In addition to encountering a potentially highly productive net gas bearing interval of 16 metres, the DRC-1 well result indicates substantial additional gas exploration potential to exist in an adjacent and up dip fault block and this will be targeted in drilling during 2015.

Due to the presence of over-pressured shales in the lower section of the well-bore, and in order to ensure that the well-bore integrity was maintained for wire-line logging operations, the well was not deepened further to the original planned TD of 1,280-metres MD.

The DRC-1 well will now be cased and cemented, and then perforated, completed and, subject to a clean-up flow period, suspended as a future gas production well.

Operations on the DRC-1 well are expected to be completed within 10 days.

The DRC-1 well is the second well to be drilled based on the interpretation of 3D seismic survey data shot by Gulfsands on the Rharb Centre Permit in 2013. The first well to be drilled based on these data, earlier this year, resulted in the discovery of gas in well LTU-1.

Upon completion of drilling operations at DRC-1, the company plans to move the rig to the Douar Ouled Balkhair drilling location (DOB-1).

The Douar Ouled Balkhair gas prospect is mapped on Gulfsands' 3D seismic survey as a fault and dip closed structural trap, and is characterised by bright seismic amplitudes and low seismic acoustic impedance signals in the same manner as was displayed by mapping on seismic of the gas reservoirs encountered in Gulfsands previous two successful gas exploration wells LTU-1 and DRC-1. The primary target sand interval lies between 808 metres MD and 870 metres MD and a secondary target interval is recognised between 973 metres MD and 1052 metres MD. The planned total depth of the DOB-1 well is 1,130-metres MD.
